A very good example of a rare polarizing binocular microcope signed “W. Watson & Sons, Ltd / 313 High Holborn / London / 40854”, circa 1920s’.
The microscope is in fine condition, complete and well preserved in its original travelling wooden box.
The microscope have its two original eyepieces for the “High Power Binocular” and three objectives (one unsigned, one Koristka and one Beck).
The microscope have some polarizing accessories : three objective analyzers and one sub-stage polarizer. There is also an objective’s diaphragme accessory and different diaphragms in brass cases.
The condition is very good excepted a crack at one analyzer.
The box measures 42x26x21 cm and this is a very heavy microscope.
